Method and device for processing postal articles

ABSTRACT

Disclosed herein are a method and device for processing postal articles. According to the disclosure, the method includes automatically verifying whether a postal article has an expected prepayment and placing a verification on the postal article where the postal article has the expected prepayment.

DESCRIPTION

The invention relates to a method for processing mailpieces, whereby the mailpieces are sorted by at least one automated sorting installation.

The invention also relates to a device that is suitable for carrying out the method.

The invention is based on the objective of determining, in the most reliable manner possible, mailpieces for which insufficient payment or no payment at all has been made.

According to the invention, this objective is achieved in that an automated checking procedure is carried out to ascertain whether the mailpiece has the expected postage and in that the completion of the checking of the mailpiece is marked by applying a code onto the mailpiece.

The payment assurance code is a marking that contains information on the result of each checking procedure that has been performed.

As a matter of principle, any payment assurance codes can be used. However, it has been found that the use of 2-digit payment assurance codes is suitable for recording all relevant payment assurance events and for integrating them into the further processing of the mailpieces, especially their sorting.

The use of such a payment assurance code can serve for further process control, for example, to systematically divert mailpieces in case of suspicion of fraud, or else to direct them to additional checking steps that differ from each other and that are a function of the payment assurance code. Moreover, the application of a payment assurance code makes it possible to ensure that a mailpiece only undergoes the payment assurance procedure once and/or that it is only recorded one single time in a mailpiece recording system.

For this purpose, it is especially advantageous that, in processing the mailpiece, a processing machine checks whether the mailpiece is marked with a payment assurance code.

An effective recording of all mailpieces that avoids double recording can be advantageously achieved in that data record components of the mailpieces that are not marked are recorded in a data processing system.

Such a processing step is, for example, a preliminary sorting in a mail center for incoming mail and in a mail center for outgoing mail.

Another processing step is, for example, a fine sorting in a mail center for incoming mail and in a mail center for outgoing mail.

Additional advantages, special features and practical refinements of the inventions ensue from the subclaims and from the following presentation of preferred embodiments of the invention.

The depicted execution forms of the method and embodiments of the device allow the recording and utilization of mailpiece-related data for the process control and for the execution of the processing steps as a function of the acquired data.

The payment assurance system according to the invention records all machine-readable mailpieces. When an uncoded mailpiece is coded as it passes through the machine, the data is stored in the payment assurance system. When a coded mailpiece is fed into the machine, then data is only recorded if an after-coding has been applied. The recognition of already existent coding is carried out by checking means which, by checking at least one surface, ascertain whether the mailpiece contains a code.

An especially suitable means for checking is offered by the expanded utilization of automation in the mail centers in order to obtain more detailed information for each automatically processed mailpiece. The result is, on the one hand, the additional diverting of mailpieces into “payment assurance compartments”. On the other hand, data from the reading and checking procedures in the machines is collected and kept on hand for the processes involving each automatically processed mailpiece.

An especially important feature is the optimization of the procedures in the mail centers and in all of the adjacent areas.

The invention makes it possible to acquire information for numerous, preferably for all, payment modalities that are possible for the mailpieces.

The checking of the types of postage can be carried out in various checking steps that are adapted to the particular type of postage.

The checking of postage generated by means of sender franking machines (SFM) is preferably carried out as follows:

First of all, the type of postage is identified and checked, in the most automated way possible.

It is especially advantageous to identify and check the type of postage in an address reading machine (ARM) or in an integrated reading and video coding machine (IRVM).

Mailpieces that, during the execution of the payment assurance process, deviate from an expected pattern, generate a payment assurance warning. Such mailpieces are handled separately, in particular, they are diverted locally from the mail sequence at a suitable place. It is especially suitable to divert them to the fine sorting machines.

Diverting the mailpieces to a fine sorting machine has the advantage that the fine sorting machine has more compartments available for the differently diverted mailpieces. This makes it possible to selectively divert the mailpieces involving different scenarios, for example, approximately 10, that have to be considered within the context of payment assurance.

When mailpieces are examined that have postage that was generated with sender franking machines, preferably all of the postage imprints are recorded.

An especially advantageous local checking of mailpieces that have been franked with sender franking machines is carried out with the criteria of the machine sorting programs, especially retroactively, optionally manually and on the basis of a positive/negative file.

The checking of mailpieces having digital postage indicia allows an especially effective checking of the proper franking of the mailpieces, thanks to the large volume of information contained in the digital postage indicia.

Due to the preferred modality of generating such digital postage in personal computers (PC), this franking modality is referred to below as PC franking. The embodiments, however, also apply to other digital postage indicia that can be generated, for example, by means of suitable large-scale printers or by franking machines that are configured for printing digital postage indicia.

Another advantage of checking the authenticity of digital postage indicia is the possibility of an automated identification and checking of the type of postage.

In particular, mailpieces are locally diverted into a sorting machine, especially into a fine sorting machine. Here, mailpieces that trigger a payment assurance warning within the scope of a checking procedure are diverted.

The further process steps take place essentially according to the preceding example.

For the payment assurance, the mailing data of the customers who frank their mailpieces by means of PC franking is compiled and supplied in compressed form. The supply of data, for example, customer data, positive and negative file, is to be integrated into the application database franking and into the Postage Point. This is where the mailing data is associated with the customer data.

The various checking methods are embodiments of a process, involving the recording of the individual mailpiece, the subsequent coding of the mailpiece as a function of the result of a step of a payment assurance method and, if applicable, the diverting of mailpieces that are suspected of non-compliance with the prescribed postage requirements.

An especially advantageous embodiment of the invention is characterized in that each mailpiece is only read once in the payment assurance system in order to prevent the mailing data from being recorded twice.

Taking preferred operational sequences into consideration, the following processes for machine-readable and machine-processable mailpieces have been defined:

-   When an uncoded mailpiece—franking modalities “sender franking     machine (SFM)” or “PC franking (PC-F)”—is coded as it passes through     the machine, the data is recorded for the payment assurance system. -   When a coded mailpiece is fed into the machine, no recording is     carried out for the payment assurance system (unless an after-coding     has been applied). -   The recognition of an already existent coding is ensured by the     technical capabilities at hand. -   Special rules apply in the case of linear code scanning.

No coding takes place in the operation mode “LCS OFF” (linear code scanning OFF). However, the postage indicium is read, evaluated and the result is recorded for the payment assurance system. In this case, mailpieces that generate a payment assurance warning can be diverted into a preliminary sorting compartment of the address reading machine (ARM).

The processing of the mailpieces in mail centers is shown below. Fundamentally, the depicted processing of the mailpieces is suitable for all mail centers.

The initial processing of a mailpiece in a mail sorting installation, especially in an address reading machine that is integrated into such an installation, results in the recording in the payment assurance system. The coding here depends on the target information and on the machine readability. The mail volumes in the reject compartment of the address reading machine, for example, are not recorded for payment assurance data. Subsequently, processing is carried out once again in the integrated reading and video coding machine (IRVM) or in the video coding machine (VCM). In this embodiment, at the end of the processing in the integrated reading and video coding machine or video coding machine, the mail volume in the reject compartment is not recorded for the payment assurance system in the outgoing mail center (OMC) operation.

After the last run, the mailpieces in the reject compartment of the integrated reading and video coding machine or video coding machine go to the residual manual sorting station.

Mailpieces with a payment assurance warning that are returned to the conveying sequence are preferably sorted in the integrated reading and video coding machine or video coding machine by the sorting program of the fine sorting machine (FSM).

Preferably, this is done in that the address reading machines and the fine sorting machines, or rather the integrated reading and video coding machines, are operated in a special mode that suppresses the sorting according to the payment assurance code contained in the code (“payment assurance (PA) OFF”).

It is likewise advantageous for the fine sorting machines (FSM), in which there are compartments for diverting the mailpieces with payment assurance features, to be provided with the function “payment assurance (PA) OFF”.

The processing of uncoded mailpieces with

-   residual manual sorting (RMS) -   E+1 COOP mailpieces (LR pre-sorting) -   mailpieces for address reading machine or integrated reading and     video coding machine (incoming mail center—IMC)     by means of the address reading machines, or the integrated reading     and video coding machines, in the incoming mail centers results in     recording in the payment assurance system of the incoming mail     center, as long as they are coded. In this case, the coding depends     on the target information and on the machine readability.

The decision as to whether a mailpiece is coded or uncoded is made by a pre-barcode reader that is integrated into the sorting installation.

It is especially advantageous for mailpieces that are already coded not to be recorded once again in the payment assurance system and, at the same time, to ensure that all of the uncoded mailpieces are (retroactively) recorded whenever possible.

It is advantageous to ensure that all payment assurance warnings that become necessary within the scope of the coding in the incoming mail center are encrypted with codes for the positions T1 and T2 that are different from the coding in the outgoing mail center. It is advantageous to also provide the function “payment assurance (PA) OFF” for the sorting and coding aggregates in the incoming mail center as well.

The mail volumes in the reject compartment of the sorting installation are not recorded for the payment assurance system and they are transported to the residual manual sorting station in the incoming mail center (IMC).

For a mail volume that was processed in the outgoing mail center (OMC) without linear code scanning and that was already recorded for the payment assurance system in the outgoing mail center, it applies that operational processing in the incoming mail center is only allowed to be carried out in the residual manual sorting station or by means of the sorting program “IMC LCS OFF”, since otherwise—due to the lack of the master code—recording in the system for additional information about mailpieces (AIM) and coding in the incoming mail center would be carried out again.

The mail volume from linear code scanning OFF programs in the outgoing mail center has to arrive at the incoming mail center in appropriately marked mail containers (MCnr) so that they can be distinguished from the mailpieces that have been recorded by the sorting installation of the incoming mail center. A sorting program “IMC LCS OFF” would prevent data from being recorded twice for the system for additional information about mailpieces because here the recording in the system for additional information about mailpieces would be switched off.

The checking steps described below are especially well-suited for carrying out the individual checking modalities.

The mailpieces are fed in a readable manner to a unit of the sorting installation, for example, a coding machine. The pre-barcode reader checks whether the mailpiece has a complete barcode. Mailpieces with complete barcodes enter the normal conveying sequence and are not recorded in the system for additional information about mailpieces. With all of the other mailpieces, the image of each mailpiece is transmitted to the image management module (IMM) and to the connected sender franking machine and 2D barcode reading unit. The image management module and the reading unit check the presented image. If it is a mailpiece with a sender franking machine (SFM) imprint, then the SFM identification and the SFM postage indicium are read.

If the sender franking machine imprint or parts thereof cannot be read, then a payment assurance warning is automatically coded and the mailpiece is diverted into the “SFM identification not readable” or “SFM postage indicium not readable” payment assurance compartments in the fine sorting machine. If the sender franking machine imprint (SFM identification and the SFM postage indicium) was read, then a procedure checks whether the sender franking machine identification has been recorded in a negative file or in a positive file and/or if the mailpiece has insufficient postage.

If the sender franking machine identification is in the negative file, then a payment assurance warning is coded and the mailpiece is diverted into the “SFM negative file” payment assurance compartment in the fine sorting machine.

If the sender franking machine identification is not in the negative file, then a procedure checks whether it is in the positive file. If the sender franking machine identification is not in the positive file, then a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “SFM not in positive file” payment assurance compartment in the fine sorting machine.

If the sender franking machine identification is in the positive file, then the amount of postage is checked. If the mailpiece has insufficient postage, then a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “SFM insufficient postage” payment assurance compartment in the fine sorting machine.

If the sender franking machine identification is not in the negative file but rather in the positive file, and if there is sufficient postage, then the mailpiece is coded without a payment assurance warning and it is fed into the normal conveying sequence.

In a preferably local database, all of the mailpieces identified as coming from a sender franking machine are recorded and the identification is registered with the appertaining postage. This data is supplied for the evaluation and issuing of the local production report.

In a local payment assurance system, a production report is issued daily, it is augmented by the results of an after-processing of the mailpieces, for example, of a local database, with the following content:

1. Time axis (evaluation after the beginning or end of the shift with a window of time of approximately 15 minutes)

2. Fine sorting machine (machine data)

3. Number of mailpieces per payment assurance event (by machine/after-processing)

4. Number of mailpieces per payment assurance compartment (by machine/after-processing)

5. Payment assurance codes

6. Additional information:

-   Number of the mail center -   Date of issue -   Beginning and end of the recording (time of day)

The local reports are transmitted to a central database (central system for additional information about mailpieces) every workday after the distribution has been completed and after the input of the supplementary entries.

In a central payment assurance unit, for example, a central database, essentially the appertaining data of several processing centers is stored and, for each sender franking machine identification, a customer production report having the following content is drawn up:

1. Time axis, for example, on the basis of the processing cycles in a mail center

2. Sender franking machine identification

3. Customer data (Uniform Customer and Product (UCP) number, name, address)—the data is made available by the franking database

4. Franking data, including the number of after-processing procedures per payment assurance amount

5. Optionally, payment assurance events and diverting data, including after-processing

6. Display of mail volume and production, including after-processing

The data of the customer production report is transmitted to the franking database in order to issue the production account report.

For each sender franking machine identification, the franking database automatically compresses its own data as well as the data that has been transmitted by the central system for additional information about mailpieces every workday:

-   cumulative postage amount spent -   cumulative amount of the paid value cards/value charges.

On a fixed schedule, the franking database compares the sum of the stamped amounts and the sum of the paid value cards/value charges for each sender franking machine identification read-in during the specified reporting period. If the results of the comparison between the read-in and the paid amounts exceed certain defined limit values, then the franking database automatically exports the data of that particular sender franking machine identification into an “alarm file” that is evaluated and further processed.

Moreover, the appertaining customer data is entered into the negative file so that it can be updated daily and transmitted to the local payment assurance system via the central payment assurance system.

Mailpieces that appear to have a digital postage indicium (PC-F) are presented to the advanced color recognizer (ACR). The advanced color recognizer analyzes the front of the mailpiece and compares patterns in an attempt to recognize a familiar type of postage (SFM, PC-F, etc.)

If PC-franking as the franking modality is recognized, the mailpiece is aligned in Compartment 1 or 2 so as to be readable for the further processing in the coding machines.

The mailpieces are fed to the coding machine so as to be readable. The pre-barcode reader checks whether the mailpiece has a complete barcode.

Mailpieces with complete barcodes enter the normal conveying sequence and are not recorded in the system for additional information about mailpieces. With all other mailpieces, the image of each mailpiece is forwarded to a central image management module (IMM) and to the connected sender franking machine and 2D-barcode reading unit. The image management module and the reading unit check the presented image. If it is a PC-franked mailpiece, the 2D-barcode is read.

If the 2D-barcode cannot be read, then a payment assurance warning is automatically coded and the mailpiece is diverted into the “PC-F negative file/barcode not readable” payment assurance compartment in the fine sorting machine.

Once the 2D-barcode has been read, and after the decryption of the cryptostring, the following checking procedures are carried out:

-   checking the PC-franking version -   checking the Postage-ID -   comparing the license number with the negative file -   comparing the hash values -   checking the date in the 2D-barcode -   checking the minimum postage

If the PC-franking version is invalid, then a payment assurance warning is coded and the mailpiece is diverted into the “PC-F version/date/insufficient postage” payment assurance compartment in the fine sorting machine.

If the PC-franking version is valid, then the Postage-ID is checked. If the postage-ID is invalid, then a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “PC-F suspicion of forgery” payment assurance compartment in the fine sorting machine.

If the Postage-ID is valid, it is automatically compared to the negative file. If the postage-ID is in the negative file, then a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “PC-F negative file/barcode not readable” payment assurance compartment in the fine sorting machine.

If the license number is not in the negative file, the hash value is compared. If the hash value is not in order, a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “PC-F suspicion of forgery” payment assurance compartment in the fine sorting machine.

If the hash value is in order, then the date in the 2D-barcode is checked. If the date in the 2D barcode differs by more than one day from the actual date, then a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “PC-F version/date/insufficient postage” payment assurance compartment in the fine sorting machine.

If the date in the 2D barcode is valid, then the minimum postage is checked. If the mailpiece has insufficient postage, a payment assurance warning is coded onto the mailpiece and the mailpiece is diverted into the “PC-F version/date/insufficient postage” payment assurance compartment in the fine sorting machine.

The system recognizes the amount of the postage from the barcode and compares it to the stored values.

If the 2D-barcode of the PC-franked mailpiece was readable, if the PC-franked version and the Postage-ID are valid and if there is no entry in the negative file, if the hash value and the date are valid and the postage is sufficient, then the mailpiece is coded without a payment assurance warning and it is fed into the normal conveying sequence.

Mailpieces for which a manual reading and checking procedure with a hand-held scanner confirms that the Postage-ID is invalid or that the hash value comparison is not correct, are correctly diverted. The mailpieces are taken out of the conveying sequence for evidentiary purposes.

Mailpieces for which a manual reading and checking procedure with a hand-held scanner confirms that the mailpiece has insufficient postage are returned to the sender or else they receive the necessary supplementary postage and are delivered to the recipient.

Mailpieces for which a manual reading and checking procedure with a hand-held scanner confirms that the Postage-ID is supplied in the negative file are removed from the conveying sequence.

In a preferably local database, all mailpieces identified as PC-F are recorded and registered. This data is provided for the evaluation and issuing of the local production report.

In a local payment assurance unit that is especially provided with a local database (local system for additional information about mailpieces), a production report—augmented by the results of an after-processing of the mailpieces—is automatically drawn up, for example, daily by the person who checks for compliance with the General Terms and Conditions, and this report has the following content:

1. Time axis (evaluation after the beginning or end of the shift with a window of time of preferably at least 15 minutes)

2. Fine sorting machine (machine data)

3. Number of mailpieces per payment assurance event (by machine/after-processing)

4. Number of mailpieces per payment assurance compartment (by machine/after-processing)

5. Payment assurance codes

6. Additional information:

-   Number of the mail center -   Date of issue -   Beginning and end of the recording (time of day)

The transmission of the local reports to the central system for additional information about mailpieces is preferably carried out every workday after the distribution has been completed and after the input of the supplementary entries.

In a central payment assurance unit, which preferably interacts with a central database, essentially the appertaining data of several processing centers is stored and, for each license number, a customer production report having the following content is drawn up:

7. Time axis (=mail center-day)

8 License number

9 Customer data (UCP number, name, address)—the data is supplied by the franking database

10. Franking data, including the number of after-processing procedures per payment assurance amount

11. Optionally payment assurance events and diverting data, including after-processing

12. Display of mail quantity and production, including after-processing

In order to be able to draw up a production-postage amount report in the franking database, the spent postage amounts calculated on the basis of the utilization profile from the Postage Point are transmitted to the database and collected there. The time intervals depend on when the customer last had contact with the Postage Point (at the latest every three months).

Once the most recently requested postage amount of every single customer has been transmitted from the Postage Point to the franking database and once the production reports for each customer are available, sorted according to license number, then the franking database automatically generates a daily updated production postage amount report, sorted according to license number:

1. License number

2. Cumulative franking amount of all mailpieces recorded in the customer production report (production value)

3. Spent postage amount calculated on the basis of the utilization profile

4. Postage amount from the Postage Point

Preferably daily, the cumulative franking amount of all mailpieces recorded in the production report for each customer is compared to the postage amount from the Postage Point and the results are stored. If the production value according to the report is higher than the postage amount, then the franking database automatically exports the customer data into an “alarm file”. Moreover, the customer data is entered into the negative file so that this file is updated daily and can be transmitted via the central payment assurance system—central system for additional information about mailpieces—to the local payment assurance system—local system for additional information about mailpieces.

A local checking means is available for the processing of the diverted mailpieces. The local checking means consists of a data acquisition unit, a graphic display unit, one or more input units, a scanner and optionally additional peripherals such as a printer for printing labels and mail scales.

This device can be employed individually in the direct vicinity of the alignment and sorting machines. The data feed or network feed takes place via existing interfaces (traffic lights) in the production.

Processing programs that are modularly adapted to the franking modalities (for example, sender franking machines and PC-franking) support the recording, evaluation and documentation of the detected franking modalities.

The connected hand scanners (wireless/hard-wired) provide information on the characteristics as well as on the decrypting of the 2D barcode with the support of a crypto-server.

The mail scales serve to check the payment, a (planned) label printer allows the production of stickers for returning mailpieces, or for printing labels to collect additional postage due.

The embodiments shown here are intended only by way of example.

The depicted method for processing mailpieces and the device shown can have a large number of different embodiments in order to fulfill different functions.

In all of the embodiments, the use of payment assurance codes provides effective protection of the postal service provider against misuse and it links this protection to comprehensive data protection of the customer of the postal service provider while ensuring full compliance with postal confidentiality requirements.

PC-F PC-franking PC-franking New form of franking at the Deutsche Post with which customers can use a conventional PC with a printer and additional software and, if applicable, hardware as well as an Internet access in order to be able to print “digital post- age indicia” onto domestic letters, etc. Postal code cluster Individual postal codes will be combined into postal code clusters within the scope of the project for additional information about mailpieces in order to reduce the data stock and to render it more transparent. Postage amount The amount that is loaded electronically into a “wallet” in the PC-franking customer system and used for the produc- tion of postage indicia. Positive file The positive file contains all of the permissible sender franking machine identifications with the appropriate postal code according to the date stamp. It is provided centrally by the FRANKING database (FDB) every day and updated by the MAIL COMMUNICATION business- customer service, in Bielefeld, Germany. Postage Point The Deutsche Post makes a Postage Point available on the Internet through which postage amounts can be loaded. Mail suppression Unauthorized removal of mailpieces from the operating sequence; criminal offense. Pre-barcode reader Component of the mail sorting installation that scans all mailpieces for the presence of codes. This makes it possi- ble to avoid double coding as well as to apply after-coding by diverting the mailpiece into a separate compartment. PS Postage stamp; type of postage RMS Residual manual sorting Key data (PC-F) The key data consists of a random number and the specification ID. The specification ID contains informa- tion on the identity of the customer, on the specification itself and on the validity of the postage indicia produced with this specification. The key data is made available in the Postage Point. Scoring model Models that automatically trigger actions in case of significant changes. Example: if the utilization pattern of a customer changes, the distribution employee in charge should be notified. SF Super-fluorescence SFS Super-fluorescence sensor Mailpieces without code Mailpieces that have no address and payment assurance coding S/Cmp Standard/compact mailpiece Mwc Mailpiece without code Super-fluorescence Substance that makes it possible to check the authenticity of postage stamps by means of a super-fluorescence sen- sor or a hand-held sensor. Super-fluorescence sensor Technical device in the alignment machine that checks the authenticity of postage stamps. Sales Economic index: sales = quantity * unit price; here: 1. Value of the conveyed mailpieces (total of individual payments of all mailpieces that have been mailed by a customer) 2. Credit purchased from the Deutsche Post by the cus- tomer (e.g. purchased value cards for a certain franking machine) Sales analysis For individual customers, the following sums (sales) are compared: ”Value of the mailpieces that have been mailed” (sum of the postage values) and payments collected from the cus- tomer (e.g. purchased value charges for franking machines). Insufficient postage Shortfall of the payment required for a mailpiece accord- ing to the General Terms and Conditions. Example: the required payment for a standard letter is 1.10 German marks, but the mailpiece is only franked with 0.80 German marks. VCM Video coding machine Verification Verification by checking the correctness. The mailpieces that are automatically diverted out of the system are checked manually by the GT&C examiner to ensure that the diverting was correct. Specification ID Number generated in the Postage Point that contains information about the identity of the customer, about the specification and about the validity of the postage indicia produced with this specification. Central distribution Employee of the central distribution control department controller (Dept. 142) in the center. AIM Additional Information about Mailpieces 

1. A method for processing mailpieces, the method comprising: (a) sorting the mailpieces by at least one automated sorting installation; (b) carrying out an automated checking procedure to ascertain whether the mailpiece has the expected postage; (c) applying a code onto the mailpiece to complete the checking Drocedure, wherein the checking procedure comprises checking whether the mailpiece is marked with a payment assurance code with a processing machine and in case the mailpiece had not already been provided with a payment assurance code, applying to the mailpiece the payment assurance code by the same processing machine.
 2. The method of claim 1, further comprising recording data record components of the mailpieces that are not marked in a data processing system.
 3. The method claim 1, wherein the sorting step (a) consists of preliminarily sorting the mailpieces in a mail center for incoming mail and in a mail center for outgoing mail.
